摘　　要：从理论上分析了内圈与轴过盈量对轴承径向游隙的影响,并在内圈与轴不同过盈量情况下对QJS207轴承进行了断油性能试验。结果表明：当轴承内圈与轴过盈量为0.014~0.015 mm时,轴承可断油运转17~19 s;当内圈与轴过盈量为0.005~0.006 mm时,轴承可断油运转30 s。The effects of magnitude of interference between inner ring and shaft on radial clearance of bearings is theo-retically analyzed,and the oil -interruption performance test for bearings QJS207 is carried out under different magni-tude of interference between inner ring and shaft.The results show that the bearings operate 1 7 ~1 9 s after oil -inter-ruption when magnitude of interference is 0.01 4 ~0.01 5 mm,30 s for 0.005 ~0.006 mm.
